The material is copper alloy,beryllium copper or aluminum bronze.Due to the good thermal conductivity of copper and high-quality stainless steel and the characteristics of almost no carbon, the heat generated in a short time is absorbed and conducted when the product is rubbed or impacted by an object.Another reason is that because copper and stainless steel are relatively soft, they have good concessions during friction and impact, and it is not easy to produce tiny metal particles.So we can hardly see the spark, the products achieve the explosion-proof effect.


Due to the softness of the copper wrench, the explosion-proof copper wrench products cannot be used in excess,not to mention the use of sleeves or tying other metal rods to lengthen the arm,further more,it can not be hammered(except for striking wrench) to screw the fasteners.

Non sparking spanners.
